Got errors when I'm trying to run this code in Eclipse

If you include the code you are running that would help you to get better feedback in the forum.

Remember, you can wrap you code in triple backticks to get Treehouse to apply some nice code styling:

```java
class HelloWorld {
public static void main (String[] args) {
System.out.println("Hello, world!");
}
}
```

will be displayed as

class HelloWorld {
    public static void main (String[] args) {
        System.out.println("Hello, world!");
    }
}

Thank you Raymond. I was confused about how to organize my code in the forum correctly, which is the reason why I didn't include my code in my question.

Yeah, they don't make it very easy to share code from what I've seen (I really wish we had line numbers). The best I've seen for Java is to do one code block per file and preface each block with the name of the file.

Something along the lines of:

Foo.java

class Foo {
}

Bar.java

class Bar {
}

I've also seen some pretty long questions with a lot of code in them so I wouldn't worry too much about length. If it really bothers you, I guess you could post each file as a code block in a comment to your question with one comment per file.
